javascript - 在 ReactJS 应用程序的生产环境中添加源映射对性能有影响吗？

Question

由于额外的服务器往返，源地图是否会影响应用程序加载时间？如果我们删除/禁用源映射，那么会有任何性能/应用程序加载时间优势吗？

它还会增加捆绑包的大小吗？

谢谢，拉梅什

Here is a link to MDN on the subject, https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Use_a_source_map

If you are adding the source maps via the commented notation, then no there will be zero impact, other than the weight of the bytes added by the comment :-)

But if you add source maps as a resource in a JavaScript file or in your HTML, then yes, the browser loads all resources linked to.

I hope that makes sense.
